Former Apprentice star Luisa Zissman has stripped off for Zoo magazine and taken a pop at Helen Flanagan's, uh, cleavage.

The busty brunette cuts a sizzling frame as she poses in just a set of racy black silk lingerie for the smouldering snaps, while also seizing on the opportunity to compare her ample assets to those of blonde bombshell Flanners .

“Apparently Helen Flanagan had the nerve to say that I’m not classy," the straight-talking star told the magazine.

"She’s got some f**king front, that girl. Every time I see a picture of her, her t*ts are out. Don’t get me wrong – I’ve got no problem with that – but mine are better than hers anyway.

"They’re the best five grand I ever spent! Maybe we should have a boob-off.”

Who do you think would win in a boob-off between the busty pair? Before you decide, have a read of their vitals...

“I did fancy Dappy a little bit. He’s cute. I can also confirm his p*nis is comparable to a magnum of Dom Perignon!

"We didn’t get it on, but I did once accidentally see it in the toilet mirror. And yes, it is the biggest I’ve seen! He’s weirdly shy about it, actually.”

She added: “I was the most sexually naughty. I don’t think they showed a lot of what I did with Jasmine.

"I don’t think they could…we made a bed away from the cameras and the microphones and we did some… stuff.

We’ve seen each other naked, put it that way. She is seriously hot – stupidly good looking – and I’ve kissed her quite a few times.

"Obviously I’d have a threesome with her, but you can’t beat a man at the end of the day, can you?”

“Because I’m the way I am, I think I allowed other people to be raunchy," Luisa continues.

"After two days in there, I was going stir crazy. The boys kept going into the shower to crack one out. I actually walked in on one of them. Everyone was at it!

"I did have a go at it in the shower myself, but I can’t climax standing up. Being in the house for three and a half weeks was very sexually frustrating, believe me. But I’m alright now – I’ve been sorted out since then!”
